[0013] In the following description, numerous specific details are set forth to provide a more thorough understanding of this utility model application. However, it will be apparent to those skilled in the art that this utility model application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this utility model application.

[0014] like Figure 1 , Figure 2 As shown, a rotatable ejector device for a guide tube includes: a connecting plate 1, a handle 2, a connecting plate 3, a frame plate 4, a bearing 5, a locking element 6, a rotating shaft 7, a slider 8, a guide rail 9, and a base. The guide tube is connected to the connecting plate 1, the connecting plate 1 is connected to the connecting plate 3, the handle 2 is located on both sides of the connecting plate 3, the connecting plate 3 is connected to the rotating shaft 7, the frame plate 4 is fitted with the bearing 5, the rotating shaft 7 is fitted with the bearing 5, the frame plate 4 is fitted with the slider 8, the slider 8 slides on the guide rail 9, the guide rail 9 is fitted on the base, and the locking element 6 is fitted on the rotating shaft 7.

[0015] In some embodiments, the base serves as the foundation of the entire device. A guide rail 9 is mounted on the base, and a slider 8 can slide on the guide rail 9, providing support and guidance for the movement of the device. A frame plate 4 is mounted on the slider 8 and moves with it. A bearing 5 is mounted on the frame plate 4, and a rotating shaft 7 is connected to the frame plate 4 via the bearing 5 to achieve rotation. A locking element 6 is mounted on the rotating shaft 7 to fix its position. When the rotating shaft is disengaged, a connecting disc 1 connects to the guide tube and is connected to a connecting plate 3. Handles 2 are located on both sides of the connecting plate 3, which is connected to the rotating shaft 7. The guide tube can be pulled and rotated by operating the handles 2.

[0016] In some embodiments, the operator can pull the connecting plate 3 with the handle 2. The connecting plate 3 drives the connecting disk 1 and the guide tube to move. The connecting plate 3 is connected to the frame plate 4 through the rotating shaft 7. The frame plate 4 is mounted on the slider 8. The slider 8 slides along the guide rail 9, thereby realizing the pulling out of the guide tube. The cooperation between the guide rail 9 and the slider 8 ensures the smoothness and directionality of the pulling out process. The pulling out length of the guide tube can be controlled by the displacement of the operating handle 2.

[0017] In some embodiments, after the guide tube is pulled out, the operator can drive the connecting plate 3 and the rotating shaft 7 to rotate through the handle 2. The rotating shaft 7 rotates smoothly under the support of the bearing 5, thereby driving the guide tube to rotate to the required angle.

[0018] In this utility model application, firstly, compared with the existing method of lifting and demolding the guide tube, the rotatable demolding device for the guide tube is pulled by a handle, and the connecting plate moves on the guide rail via a slider, thereby pulling out the guide tube. The length of the guide tube pulled out is controllable, avoiding excessive pulling force and over-pulling of the guide tube. It does not require complex hoisting equipment or power systems, has low manufacturing and maintenance costs, and saves hoisting operation time. In addition, the mechanical structure realizes the pulling out and rotation of the guide tube, eliminating the need for the old-fashioned method of using a hoist to lift the guide tube for cleaning operations, avoiding the risk of the guide tube falling and causing high-temperature burns during hoisting operations, reducing safety hazards, and ensuring the safety of operators.

[0019] Optionally, there are two sliders 8, the rotating shaft 7 is located between the two sliders 8, there are two guide rails 9, there are two handles 2, the bearing is a thrust ball bearing, and the locking element 6 is a nut.

[0020] In some embodiments, the connecting plate 3 may be provided with multiple first locking holes, and the frame plate 4 may be provided with multiple second locking holes. The locking rod can pass through the first locking holes and the second locking holes to lock the connecting plate 3 and the frame plate 4. The operator can hold the two handles 2 at the same time, and the two sliders 8 slide along the two guide rails 9 to pull the connecting plate 1 and the guide tube out of the mold. The operator can also rotate the handles 2 to rotate the connecting plate 3 and the rotating shaft 7, adjust the angle of the guide tube, and after the guide tube reaches the designated position, the locking rod can pass through the first locking holes and the second locking holes to lock the connecting plate 3 and the frame plate 4, thereby preventing the connecting plate 3 from rotating in the opposite direction.

[0021] In this utility model application, the design of two sliders 8 and two guide rails 9 increases the support points for movement. The rotating shaft 7 is located between the two sliders 8, making two-hand operation more convenient and avoiding the tilting or offset that may occur with a single slider. This ensures the precise movement direction of the guide tube. The bearing 5 adopts a thrust ball bearing, which can withstand the axial load of the rotating shaft 7 while ensuring smooth rotation. The double sliders, double guide rails, thrust ball bearings, and nuts are all standard mechanical parts, which are simple to manufacture and maintain low manufacturing and maintenance costs, making them suitable for large-scale production applications.

[0022] Optionally, the connecting plate 1 is provided with multiple mounting holes, and the guide tube is connected to the connecting plate 1 through the multiple mounting holes.

[0023] In some embodiments, multiple mounting holes provide various fixing methods for the installation of the guide tube, which can be quickly installed using simple fasteners such as bolts and pins. This simplifies the installation and disassembly process of the guide tube, reduces operation time, and improves production efficiency.

[0024] In this utility model application, firstly, multiple mounting holes allow the guide tube to be connected to the connecting plate 1 through multiple fixing points, increasing the contact area and the number of fixing points, improving the connection reliability between the guide tube and the connecting plate 1, and preventing the guide tube from loosening or falling off during pulling or rotating; secondly, the design of multiple mounting holes (exemplarily, multiple mounting holes include multiple sets of annular holes) can also adapt to guide tubes of different sizes or shapes. By selecting different hole positions for installation, various guide tube specifications can be flexibly adapted to meet different production needs.

[0025] The working method of the rotatable ejector device for the guide tube of this utility model application is as follows:

[0026] First, connect the connecting plate 1 to the extruder's guide tube with hex bolts. Next, hold the handle with both hands and pull it to move the connecting plate 1 and the frame plate 4 along the guide rail via the slider, thereby pulling out the guide tube. The length of the guide tube pulled out can be set according to actual needs. Then, hold the handle with both hands and turn it to rotate the rotating shaft 7. The rotation angle can be set according to actual needs. After rotating to the designated position, prevent the connecting plate 3 from rotating in the opposite direction. This allows for cleaning, maintenance, or inspection of the guide tube. After cleaning, maintenance, or inspection, repeat the above steps in reverse to restore the original state.

[0027] As stated above, although this utility model application has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the utility model application itself. Various changes in form and detail may be made to this utility model application without departing from the spirit and scope of the appended claims as defined.
